WEATHER STRIP.

Application filed January 19, 1924.

My invention relates to improvements on weather strips. One of itsobjects is to provide an improved sheet metal weather strip adapted tobe applied to windows, doors, and

similar openings where it is important to exclude the passage of waterand cold air at the joints during cold and wet weather. An-

other object is to provide an improved all metal Weatherstrip adapted tomore perfectly close the joints and exclude rain and cold air. Anotherobject is to provide an improved weather strip adapted by its outline,shape and relation of parts to more per fectly and persistently retainits original outline and to thereby more perfectly perform its functionand for longer periods of time, and to more perfectly meet the varyingconditions of practical application. My invention also comprisescertain. details of form and combination of components, all of whichwill be fully set forth in the description of the accompanying drawings,in which:

Fig. 1 is a perspective view of a section of sheet metal weather stripembodying my invention.

Fig. 2 is a horizontal section through one side of a window frame andsash illustrating the application of my improved weather strip thereto.

Fig. 3 is a horizontal sectional detail through one side of a door frameand door illustrating the application of my improved weather stripthereto} Figs. i and 5 are sectional details illustrating the rangeapplication of my improved weather strip.

The accompanying drawings illustrate the preferred embodiment of myinvention in which the weather strip is formed by bending or foldinguoon itself a relatively narrow strip, of resilient sheet metal or otherresilient material longitudinally thereof along a line 20. The line ispreferably so located with reference to the width of the strip that arelatively narrow leaf or blade 22 is preferably bent outwardly from thebase sections 21 along the line 40 and is adapted to bear yieldinglyagainst one face of the joint, say against the face 24 of the windowframe 25. In Fig. 2 a relatively wider leaf or blade 26 is adapted tobear yieldingly against the opposite face of the joint, say against theface 27 of the window sash 28.

In order that the leaf 26 may be better Serial No. 687,339.

adapted to retain its shape, and also that it may engage more perfectlyand satisfactorily with the joint to be closed, and in order that it maymore perfectly engage and disengage with the joint to be closed wheresuch action is required, said leaf 26 is curved transversely of itslength into substantially a section of a cylindrical body, and at itsfree end 30 is preferably turned upon itself to provide a smooth bindingor finished edge adapted to slide freely along either face of the jointto be closed, without liability to catch or bind thereon. Thus where thejoint to be closed is narrow the middle section of the curved leaf 26 isadapted to engage firmly against one face of the joint, say the face 27of Fig. 2, while the two opposite edges 30 and 2-31 of said curved leafboth tend to react against the pressure on the joint face 27 and topress against the joint face 24: to doubly and more effectually closethe joint between the sash and window frame. Substantially the sameaction will be had to close the joint bet-ween a door and door frame asshown in Fig. 3 for instance:

The base member 21 serves as a point of attachment for the weatherstrip, which is preferably effected by means of screws or nails 23passing through perforations in the base member 21 at intervals and intothe window frame or door frame. Normally the spring action of the leaf22 is to lift the base of the leaf 22 along line 40, and also the baseof the leaf 26 at 31 away from the face of the joint to which the basemember 21 is attached by the screws 23 and thereby affords a moreresilient hearing or contact of the leaf members 22 and 26 against theopposite joint surfaces, and thereby affords a more effective andperfect weather protection'than would be otherwise attainable.

iVhcre, however, the joint to be closed is relatively wide, as shown forinstance at Fig. 5. a portion of the curved face of leaf 26 will bearagainst one joint face 32 and the base of the leaf 26 at 31 will bear indirectly against the joint face 33, while the end, 30 of the leaf 26will remain out of contact with the joint face 33. The curved outline ofthe leaf 26, as indicated in Fig. 3, tends to more readily make andbreak the joint between the free or moving edge or face 35 of a door andthe face 36 of the jamb of the door frame 37, substantially as abovedescribed, to secure either a single or double engagement of the leaf 26i l curved or (;".lll1-il i "l outline ot the lent ana s "Hill lea l' toselectively make roata 't at (Ellerent poin s along' its curved lace.and tends in prev nt dents being toranc in the ta e lherwtJand tends tosernre torn; and continnons engagement (i' a l e-:1." w th one or hothot the ta s o 2' r to l? clef (l even though the joint 1" -.i la: oneend than at he other. he inntna ion ot the two diiewz ng resilientleave. and 2e and their uniting and 1.1;: aaanher is such that said memlers do not lose thei re iliency in nse. even nnder severe and 'epeatezlpressure or slraiin and hence retaii and return to" l J l i nalpositionfn ien strain thereon 'lhe positions oi the strip in their om.
